Types of implementations




## <a name="CRandBytes">func</a> [CRandBytes](/src/target/random.go?s=698:734#L28)
``` go
func CRandBytes(numBytes int) []byte
```
This uses the OS and the Seed(s).



## <a name="CRandHex">func</a> [CRandHex](/src/target/random.go?s=924:959#L38)
``` go
func CRandHex(numDigits int) string
```
RandHex(24) gives 96 bits of randomness, strong enough for most purposes.



## <a name="CReader">func</a> [CReader](/src/target/random.go?s=1078:1102#L43)
``` go
func CReader() io.Reader
```
Returns a crand.Reader mixed with user-supplied entropy



## <a name="DecodeArmor">func</a> [DecodeArmor](/src/target/armor.go?s=596:699#L18)

## <a name="DecryptSymmetric">func</a> [DecryptSymmetric](/src/target/symmetric.go?s=1048:1133#L23)
``` go
func DecryptSymmetric(ciphertext []byte, secret []byte) (plaintext []byte, err error)
```
secret must be 32 bytes long. Use something like Sha256(Bcrypt(passphrase))
The ciphertext is (secretbox.Overhead + 24) bytes longer than the plaintext.



## <a name="EncodeArmor">func</a> [EncodeArmor](/src/target/armor.go?s=125:206#L1)
``` go
func EncodeArmor(blockType string, headers map[string]string, data []byte) string

secret must be 32 bytes long. Use something like Sha256(Bcrypt(passphrase))
The ciphertext is (secretbox.Overhead + 24) bytes longer than the plaintext.
NOTE: call crypto.MixEntropy() first.



## <a name="MixEntropy">func</a> [MixEntropy](/src/target/random.go?s=407:440#L13)
``` go
func MixEntropy(seedBytes []byte)
```
Mix additional bytes of randomness, e.g. from hardware, user-input, etc.
It is OK to call it multiple times.  It does not diminish security.

``` go
func Ripemd160(bytes []byte) []byte
